To monitor the voltage of a given source you need a voltage sensor. A gpio pin is a way to start on either a raspberry pi or an Arduino.

We started with this approach but the voltage competitor on the devices is far to inaccurate for reliable voltage detection. The program must compare the voltage read of the gpio in pin against a know voltage to get an accurate voltage to display and/or record to the database.

On this quest we found devices on Ebay for testing

  • PCF8591 Module Analog to Digital Converter Module

  • adurino 25 volt resistor bridge.
